1 '0 all whom it may concern.

Be it known that I, SAMUEL G. RICHTER, a citizen of the United States,residing at Doltons Station, in the county of Cook and State ofIllinois, have invented new and useful Improvements in Turn-Table Locksand Derailer Controls, of which the following is a full, clear, andexactdescription.

My invention relates to safety devices for railroad tracks, andparticularly for preventing the wrecking of engines, locomotires andrailway cars in turntable pits and at swinging bridges.

The object of my invention is to derail a locomotive or a car before itcan reach the pit of an open turntable or the stream or depressioncrossed by a bridge, at such a distance therefrom that the wrecking ofthe same will be avoided, and it is also an object of my invention to dothis by comparatively simple means which will set the derailer on theball of the track at the same time the bolt or locking device of saidturntable or bridge is manipulated to permit the latter to be moved andunset it when the turntable or bridge is locked. These and other objcctsare accomplished by the means hereinafter fully described, and asparticularly set forth in the claims.

In the drawings:

Figure 1 is a plan view of broken away portions of the track approachand the end of a turntable showing my improvements applied thereto.

Fig. 2 is a longitudinal view of the same taken on dotted line 2-2, Fig.1.

Fig. 3 is a longitudinal section taken on dotted line 3-3, Fig. 1, drawnto a larger scale.

Fig. 1 is a horizontal section taken on dotted line 4l, Fig. 3.

Fig. 5 is a transverse vertical section taken on dotted line 55, Fig. 1,drawn to the same scale as Fig. 3.

Fig. 6 shows a transverse section of one of the rails of the approachingtrack looking toward the derailer, which latter is shown in dottedlines, while its seat is shown in solid lines.

Referring to the drawings, A represents a circular turntable pit; B ,aturntable having ties b, 7), connecting the parallel beams of the framethereof; C, C, the rails mounted on said ties and D, D, the rails of thetrack approaching said pit.

My improvements comprise, broadly speaking, a longitudinallyreciprocable bolt 8, which is mounted on the turntable between andparallel to rails C, C; a tubular casing 9 arranged longitudinallybetween tracks D, D, into which said bolt is adapted to be shot; aderailer 10 located fifty to seventyfive feet away from pit A, andmechanism that utilizes the thrust of the bolt when it is shot into saidtubular casing 9 to move the derailer off of the track so as to leave anopen track when the turntable is locked to bring rails C, C, and D, D,in alinement preparatory to running a locomotive or car onto saidturntable, and to reset said derailer on the track when the bolt iswithdrawn from said casing and the turntable is moved so as to carryrails C, C, out of alinement with rails D, D, of said approaching track.

As shown in the drawings, bolt Sis a comparatively long metal bar thatis mounted upon the ties parallel to rails C and reciprocated throughthe medium of a link 12 connecting it to an arm 13, which latterprojects upwardly from a rock-shaft 1 1 journaled in suitable hangers 15secured to and depending down from the longitudinal beams or equivalentstructure of the frame of the turntable, substantially as shown in Fig.2 of the drawings. Bolt 8 is placed between and its reciprocablemovement is guided by means of guide-plates 16, 16, and 17, 17;guide-plates 16 having flanges that overlap the longitudinal edges ofthe bolt and guide-plates 17 having flanges upon which said bolt rests.This arrangement of the overlapping and underlapping flanges ofguide-plates 16 and 17 is provided for the purpose of permitting of acertain limited vertical play of the end of bolt 8 nearest the end ofthe turntable, where the bolt has securely mounted thereon alongitudinally disposed plate 18, the advanced end of which extendsbeyond the adjacent end of the bolt and is formed into a hook 19, theextremity of which points downward and terminates in a horizontal planea suitable distance above the horizontal plane of the top of the bolt.If desired, this hook may be strengthened by the roe employment of ribsarising from its longitudinal edges and the corresponding edges of plate18, substantially as shown.

Tubular casing 9 is, preferably, rectangular in cross-section, and itsbase-plate or bottom 20 extends beyond the end thereof into which thehooked end of the bolt is adapted to enter, and when. the casing isarranged in proper position the end of this extension terminates at theedge of the pit, substantially as shown in Fig. 3, and is, preferably,slightly beveled. The adjacent end of the bolt is provided with aslightly undercut bevelso that when said bolt is shot toward theadjacent open end or mouth of easing 9 it will be slightly raised.

The inner surfaces of the vertical walls and the roof of the casing arebeveled at its mouth, and the upper portion of said vertical walls aremade thicker and provided with longitudinal runways 22 that extend fromits rear end to very near its mouth. Near said mouth these runways areinclined downward and terminate in and communicate with the longitudinalgrooves in the said Vertical walls next the floor of the casing thatresult from and are incidental to making'the upper portions of saidwalls thicker. These runways may be made in any other way, but,considering the rough usage to which the casing is subjected, I preferto make them as hereinbefore described.

Arranged and movable longitudinal within casing 9 is a dog 23 consistingof a suitably shaped metal bar of a length substantially correspondingto that of the bore of the casing. The end of this dog nearest the boltis provided with a transverse ric ge 2-]: projecting upward therefrom,the ends of which are extended to provide lugs 25, 25. The under sidesof these lugs are in a horizontal plane corresponding to the lower edgeof the thickened upper portion of the vertical walls of the casing, andthe rear portions of these bottom edges are beveled, as shown at 26,Fig. 3 of the drawings. The rear end of dog 23 is connected by alongitudinally extending rod or pipe line 27 of about fifty toseventy-five feet in. length to the longer arm of a bell-crank 28, whichlatter is fulcrumed at its angle to a suitable pivotal stud 29 securedto and arising from a plate secured to one end of the ties of the track,and the shorter arm of this bell-crank is pivotally connected to theadjacent end of a transversely extending link 30 whose opposite end isconnected to a lug projecting down from the derail block 31, theopposite end of which latter is suitably shaped to derail a locomotiveor car when it is moved transversely onto the tread of rail D whenLetters Patent of the United States, g 'anted to S. W. Hayes, for derailOct. 31, 1911, No. 1,007,102 and June 6, 1916, No. 1,185,663 and asshown in outline in Fig. 6 of the drawings, but it will be understoodthat any other derailing block or device which can be moved laterally toset on the tread of the rail to derail a locomotive or car passing overit will answer the purpose of my invention just as well as said block31, and I, therefore, do not wish to be confined to the use of the same.

Casing 9 is retained in the position shown in the drawings in alinementwith belt 8 by means of triangular shaped guide-plates 32, 32, betweenwhich the end of the casing nearest the bolt is placed, and in order topermit of a limited vertical play of said easing I have provided thevertical retaining walls 33 of said plates with vertically elongatedguide-openings 3st into which guidelugs 85, 35, projecting laterallyfrom said casing, enter and have a limited vertical play.

In order to operate my invention, rockshaft 1% is moved through themedium of a lever 36 secured to and projecting from one end thereof inone direction and imparts a movement to said shaft and to arm 13, which,through the medium of link 12, shoots bolt 8 toward casing 9 so that thehooked end 19 thereof will enter the adjacent mouth of the same. IVhensaid bolt has been shot forward a sufiicient distance the end of thesame below the horizontal plane of the extremity of hook 19 will come incontact with the adjacent end of dog 23 and as it continues to move inthe same direction it moves the dog rearwardly, and lugs 25 at the endsof ridge 24 thereof enter the adjacent ends of runways 22 and raise theadjacent end of said dog so that said ridge enters within the embrace ofhook 1S) and interlocks therewith. Dog 23 as it is thus moved to therear moves pipe line 27 longitudinally and imparts motion to bellcrank28, which latter through the medium of link 30 moves the derailing blockoff of rail D of the approaching track. lVhen the turntable is thuslocked so that the approaching track is open and alines with the trackon the turntable, the locomotive or car can be run onto the turntable,and when in proper position the latter can be unlocked and turned tobring it into alinement with some other track that approaches theturntable pit and the locomotive or car can be run onto the same.

In order to unlock the turntable, lever 36 is moved so as to rock shaft1 1 in the opposite direction to that just described, and through themedium of arm 13 and link 12 withdraws bolt 8 from the casing. As thehooked end of this bolt is thus withdrawn it pulls dog 23 along with ituntil the ridged end thereof is directed downward by the inclinedforward portion of runways 22, whereupon it releases its hold upon thebolt, which latter continues its withdrawal movement until thecontiguous end thereof passes and clears the junction between'the end ofthe turntable and the edge of the pit. As dog 23 is pulledlongitudinally forward toward the pit by the hooked end of the bolt, asjust stated, pipe line 27 moves bell-crank so that it, through themedium of link 30 moves the derail block so that the derailed endthereof is reset on the ball of rail D. 7 hen the derail block is inthis reset position, any locomotive or car attempting to pass over thesame will be derailed and immediately stopped by the engineer, and thusprevented from pitching into the turntable pit and wrecked.
